..there are many charts like this that seems to suggest a disconnect, with a conclusion that something else is causing obesity and not sugar.
..obesity can also be caused by other factors (sedentary etc) other than sugar, but it does not absolve sugar being a major contributor to obesity.
A simulation like this can explain it

There can be a gain in % of people becoming obese from 30% to 38% with average consumption of grams/pp remaining the same. But with majority of 62% of people reducing their consumption by 40% over the years.
The younger people consume less sugar so the disconnect is explained by a bipolarity between two groups of consumers - one that continue to consume in high proportions and another that has reduced consumption.
This like many others reflect a generational divide in thinking and consumer preferences. So if we put our own assessment to task, we could conclude wrongly.
